5 Teaching of the Measuring Range
Every sensor is delivered with the factory setup (max. measuring range). The teach-in feature was designed to
choose a smaller range within the nominal measuring range for optimizing the resolution and linearity. Output cur-
rent, voltage and alarm output adapt to the new range. Two positions must be taught.
•
The first teach-in position aligns with 0V (or 4mA), the second position aligns with 10V (or 20mA)
•
These teach-in positions are always just at the border of the new range (inside the measuring range)
•
The sensor may be taught more than 10,000 times in its lifetime
•
The sensor can always be reset to the factory settings
•
The sensor may be taught with the teach button or via the external teach input
•
During the teach-in process, the red LED provides a feedback
•
The red LED on the back side of the sensor indicates “run” mode if an object is within the measuring range.
Attention:
Within 5 minutes after power on, the sensor can be taught via the button or the teach-in wire. After 5 minutes, the
teach-in button will be locked preventing accidental adjustment. The teach-in wire is active all the time.
Example of a taught measuring range
(4mA / 0V near, 20mA /10V far)
Example of a reverse taught measuring range
(4mA / 0V far, 20mA /10V near)
